Worked my way through the 'Method Member' tests for the 'goog'-ified JS implementation. In order to get the function block closing semicolon in place, I've 'rerouted' some stuff in the AS and JS emitter base classes. I put comments on the relevant sections, please check my implementation and feel free to give brutal feedback :-)
